When you chose the company of a saint, you chose uncertainties also. That's actually the essence of life. Saints live impermanence externally and experience permanence internally. This is the irony. They enjoy the growth and decay of cells, and do nothing about it, even if they had the power to change, reverse or recreate anything. When you are with the truth, you also possess the power of the supreme truth. That becomes part of your existence. Yet, you will do nothing for yourself. That's the way true Masters are. They need nothing. No favors nor sacrifices. They live as moving monuments of selflessness. As signposts of liberation.
